The Saucony Triumph ISO 5 is great for punishing workouts on the road and long-distance triathlons. You could say, this shoe is a necessity for Ironman training.
The SPIRE 3 is the third edition of the SPIRE shoe, a neutral lightweight endurance trainer. It is ideal for triathletes looking for a shoe that will withstand the pounding of an Ironman while delivering lightweight performance. Not doing an Ironman anytime soon? Don’t worry. The SPIRE 3 is a great shoe to rack up the mileage this summer.
